The potential 1960s-set series is called Max and, according to The Hollywood Reporter, centers on a magazine writer who “stumbles into the women’s movement during second wave feminism.” Lisa Joyce (Wallflowers, Boardwalk Empire) is set to star as the title character in the pilot, which Dunham will direct herself.

The pilot is being written by Girls writer-producer Murray Miller and executive produced by Dunham’s Girls collaborators Jenni Konner and Ilene Landress.

Dunham is also working on another HBO project—a documentary about Bindle & Keep, a bespoke-tailoring company that is popular in the L.G.B.T.Q. community, called Three Suits.
